Medical cannabis for ALS — patient guide in Puerto Rico

Why it may help

Amyotrophic lateral sclerosis (ALS) progressively damages the motor neurons that control voluntary muscle movement, and along the way patients often develop painful muscle spasticity, cramping, and disrupted sleep. The body's endocannabinoid system — its CB1 and CB2 receptors and natural messengers like anandamide — helps regulate muscle tone, pain signaling, and the inflammatory activity of the immune cells surrounding nerve tissue. Researchers are studying whether plant cannabinoids such as THC and CBD may interact with these receptors to calm overactive muscle-tone signaling and modulate the pain and inflammatory pathways involved, though how this affects the underlying disease is still unknown.

How patients use it

People living with ALS who explore medical cannabis are usually seeking relief from the symptoms that erode day-to-day comfort — muscle stiffness and spasticity, cramping, pain, poor sleep, and excess saliva. Research suggests that by acting on the endocannabinoid system, certain cannabinoids may help ease spasticity and cramping and support more restful sleep for some patients. Cannabis is used here for symptom comfort, not to slow or reverse the disease, and any plan should be closely coordinated with the neurology team.

Strength of the evidence

The scientific evidence for cannabis in ALS is limited and still emerging — small studies have explored relief of spasticity and related symptoms, and it draws on the stronger evidence for cannabinoids in multiple sclerosis spasticity, but high-quality trials specific to ALS remain few.
